摘　　要：[目的]分析微生态制剂治疗奶牛瘤胃酸中毒的效果。[方法]选择山东地区某规模化奶牛养殖场200头中国荷斯坦牛作为试验对象,随机分为对照组和试验组两组,每组10个重复,每个重复10头奶牛。对照组给予基础日粮,试验组在基础日粮中额外添加2.0%复合微生态制剂,比较分析两组奶牛生长性能、泌乳性能及瘤胃发酵性能的差异显著性。[结果]添加微生态制剂的试验组平均日增重比对照组显著增加(P<0.05),料重比显著小于对照组(P<0.05),平均日产奶量、乳脂率显著高于对照组(P<0.05)。微生态制剂试验组瘤胃液pH值、乙酸含量、丙酸含量、丁酸含量显著升高(P<0.05),乳酸含量、乙酸/丙酸比值显著低于对照组(P<0.05)。[结论]应用2.0%复合微生态制剂添加饲喂能有效缓解奶牛瘤胃酸中毒,为今后高效科学治疗奶牛瘤胃酸中毒提供了参考。[Objective]To analyze the effect of probiotics on treating rumen acidosis of cows.[Method]200 Chinese Holstein cows from a large-scale dairy farm in Shandong Province were selected as the experimental subjects.These cows were randomly divided into control group and experimental group with 10 replicates in each group and each replicate contains 10 cows.The control group was fed with a basic diet,and the experimental group was supplemented with 2.0% compound probiotics on the basis of basic diet.The significant differences in growth performance,lactation performance and rumen fermentation performance between two groups were compared and analyzed.[Result]The average daily weight gain of experimental group treated with probiotics was significantly increased compared to the control group(P<0.05),and the feed to weight ratio was also significantly lower than that of the control group(P<0.05).The average daily milk yield and milk fat percentage of experimental group were significantly higher than those of control group(P<0.05).The pH value,acetic acid content,propionic acid content and butyric acid content of rumen fluid in the experimental group were significantly increased(P<0.05).Lactic acid content and acetic acid/propionic acid ratio in experimental group were significantly lower than those in control group(P<0.05).[Conclusion]The application of 2.0% compound probiotics could effectively relieve rumen acidosis of cows,which provided a reference for the efficient and scientific treatment of cow rumen acidosis in the future.
